Definitions

  • the invention relates to a branch pipe part, more particularly a plastics branch pipe part for connecting a supply or discharge conduit to a main conduit, the lower end of said branch pipe part to be inserted into an opening of a main conduit at least comprising a first outwardly extending projection and an annular space for receiving an annular sealing member.
  • a branch pipe part of this type is known in the art.
  • Said known branch pipe part presents the drawback that the construction of the same is complicated and that narrow tolerances have to be maintained as regards the opening to be formed in the main conduit, whilst furthermore, said branch pipe parts are insufficiently resistant to transverse forces and bending forces executed upon them.
  • the present invention aims to provide a branch pipe part of the abovementioned type, which does not have said drawbacks.
  • a reliable connection between a branch pipe part, more particularly a plastics branch pipe part and a main conduit is obtained by pushing a deformation-preventing bush into the branch pipe part after mounting. This bush prevents a substantial further deformation of the deformable part so that the first outwardly extending projection is locked in the main conduit.
  • a good instalment of a bush of said type in the branch pipe part is ensured by providing one side of said bush with a collar, which engages an abutment edge in the branch pipe part when said bush has been pushed into said branch pipe part, the latter advantageously being provided with a positioning member, e.g. in the form of a groove, which may cooperate with positioning member part of the bush, e.g. in the form of a cam; obviously the branch pipe part may be provided with a cam and the bush with a groove.
  • the annular abutment edge allows an instalment of the bush into the branch pipe part at the appropriate height, the respective groove and cam effecting an appropriate position of the bush in the branch pipe part.
  • the branch pipe part according to the invention advantageously comprises incisions in order to obtain a deformable portion, said incisions preferably being longitudinal incisions.
  • the branch pipe part according to the invention is advantageously_provided with an annular collar, in order to maintain an annular sealing member between the outer side of the main conduit and the relative collar.
  • An optimum seal to be obtained by means of a simple sealing ring is effected by advantageously providing the annular collar with a downwardly extending skirt, thus forming a securing groove into which the sealing ring may be enclosed.
  • the presence of a securing groove allows a flat sealing ring to be retained in a curved plane, corresponding to the outer wall of the main conduit with respect to the branch pipe part.
  • An extreme advantage can further be attained by combining the respective branch pipe part according to the present invention with an element as known from Netherlands patent application 78 03400.
  • the distance between a main conduit and a road surface may then be restricted considerably, as in that case only the height of the branch pipe part is required, This 'is of great importance in separated sewer systems in which rain water is mostly discharged through a separate main conduit located in the vicinity of the road surface.
  • Figure 1 shows a branch pipe part 1 for connecting a main pipe conduit 2 to a branch conduit 3.
  • the inner side of said branch pipe part comprises an abutment edge 4 and the outer side of said branch pipe part is provided with a projection 5 in the form of a collar, at its free extremity 11.
  • an outer circular collar 6 is provided at distance from and on a higher level than the free extremity 11.
  • the space between projection 5 and circular collar 6 is adapted to receive the wall of a main conduit 2 and an annular sealing member 18. Longitudinal incisions 10 in the branch pipe part 1 allow the lower side of said branch pipe part to become deformable, so that the outwardly extending projection 5 is able to pass the edge 8 of an opening in the main conduit 2.
  • Said longitudinal incisions 10 extend from the free extremity 11 of the branch pipe part 1 to a region 12, situated at a level lower than the circular collar 6.
  • Said circular collar 6 comprises a downwardly extending skirt 14 which may preferably be provided with an inwardly directed skirt projection 15.
  • An annular space 17 designed to receive an annular sealing member 18 is bounded by the skirt 14 and the circular collar 6 (see also fig. 1 and 3); said sealing member 18 may be provided with projecting ribs.
  • Fig. 4 shows a modified embodiment of a sealing member 18, the inwardly directed skirt projection 15 for appropriately retaining the annular sealing member 18, is now not present.
  • Said bush 19 preferably comprises a shoulder 21 engaging the abutment edge 4, when being slid into the branch pipe part, so that the sliding distance of the deformation avoiding bush 19 is limited.
  • bush 19 comprises a cam 25 in the form of a positioning member part engaging a groove 9 in the form of a positioning member provided in branch pipe part 1.
  • said cam 25 may also be provided upon the branch pipe part 1 while groove 9 will then be provided upon the bush 19.
  • the position of branch line 3 is also bounded by the abutment edge 4 or by the projecting shoulder 21, which engages said abutment edge 4 (fig. 1).
  • an additional abutment edge 26 is provided at a socket end of said branch pipe part, a stretchable bush 27 as described in Netherlands Patent Application No. 78 03400 resting against said additional abutment edge 26.
  • the stretchable bush 27 of a polyolefin such as polyethylene or polypropylene, will yield, so that the branch conduit, notwithstanding any ground shifts, will not be impaired.
  • a shoulder 21 bounds the axial displacement of the branch line 3.
  • a sealing sleeve 22 is used in order to simply fix branch line 3, the front end 23 of said sealing sleeve being retained by a retaining ring 24, which is fastened in an axial displaceable way upon the outer side of the branch pipe part 1.
  • the latter Due to the obliquely extending upper surface of the circular first outwardly extending projection 5, the latter comprises a slightly engaging upper edge 8a, which additionally prevents an undesired displacement of the branch pipe part 1. (see fig. 1).
  • Figure 7 shows an embodiment in which, after instalment the bush 19 cannot be pulled out as the upper edge 26 of cam 25 is hooked behind the end edge 27 of an incision 10.
  • the height of the cam is greater than the depth of the groove 9 and the lower edge 28 of said cam 25 is chamfered.
  • the sealing ring may be provided with lips 30 extending through apertures 29 in collar 6. These lips 30 retain the sealing ring 18 in space 17.
  • sealing member 18 For an improved sealing it may be advantageous to provide the sealing member 18 with sealing member legs 18a, 18b, 18c and 18d.
  • the adapting ring 31 preferably of a polyolefin, such as polypropylene, is provided with at least one ear 35 for indicating the class of the main pipe 2, in case of using the branch piece with the adapting ring 31.
  • At least one ear 36 of adapting ring 31 provides the information for removing the adapting ring 31
  • an ear 34 of the rubber sealing member 18 provides the information about the class of pipe to be used with the branch piece after removal of adapting ring 31.
  • the adapting ring 31 comprises an intermediate part 32 engaging the lower free end 37 of skirt 14, said intermediate part having an upstanding inner edge 33 engaging the inner side of the skirt 14.
  • a leg 18c of sealing member 18 engages the intermediate part 32.
  • leg 18b is also deformed in a horizontal plane and the last leg 18c is always tightly engaging the outer side of the main pipe conduit 2 and either the lower free end of skirt 14 or the bottom side 38 of the intermediate part 32 of compressing ring 31.
  • FIG. 7 A very preferred embodiment is shown in fig. 7 which is combined with an appropriate adapting ring 31 and a sealing member 18 with lips 30 as shown in figure 9.
  • the branch piece consists preferably of a thermoplastics such as polyvinylchloride.
